She also detailed the story of her romance with fiancé Alexis Ohanian in an article for the magazine.
The 23-time Grand Slam singles champ is shown in profile facing left with her right arm covering her breasts and her pregnant stomach proudly displayed, a small waist chain the only item she wore.
Serena said in the story she learned she was pregnant just before the Australian Open, which she won.
She revealed in April she was pregnant and hasn’t played again since. In the story, she insists she will return to tennis in January, which would allow her to defend her Australian Open crown.
Serena and Alexis, the 34-year-old co-founder of social media website Reddit, will be married this year after the baby’s birth, says the article. They announced their engagement in December after meeting in 2015 in Rome.
After throwing up and her breasts becoming enlarged after a poor showing in her first match of the season in Australia, Serena took a pregnancy test.
She was getting ready to go out and “went back to finishing hair and makeup, was laughing, talking. I was getting the styling done. An hour and a half later, I went back to the bathroom and I totally forgot about it because it was impossible for me.”
When she finally looked at the test, she “did a double take and my heart dropped. Like literally it dropped”.
